Class CIM_BlockStorageStatisticalData
extends CIM_StatisticalData

A subclass of StatisticalData which identifies individual statistics for an element of a block storage system. This class defines the metrics that MAY be kept for managed elements of the system.

ElementTypeuint16
DescriptionstringDefines the role that the element played for which this statistics record was collected. If the metered element is a system or a component of a system associated to a RegisteredProfile, then that profile may provide a more specialized definition and additional usage information for this property. Generally, the ElementTypes defined here have the following meaning in the context of this class: 2, "Computer System": Cumulative statistics for the storage system. In the case of a complex system with multiple component Computer Systems, these are the statistics for the top-level aggregate Computer System. 3, "Front-end Computer System": Statistics for a component computer system that communicate with systems that initiate IO requests. 4, "Peer Computer System": Statistics for a component computer system that communicates with peer storage systems e.g. to provide remote mirroring of a volume. 5, "Back-end Computer System": Statistics for a component computer system that communicates with back-end storage. 6, "Front-end Port": Statistics for a port that communicates with systems that initiate IO requests. 7, "Back-end Port": Statistics for a port that initiates IO requests to storage devices. 8, "Volume": Statistics for an exposable storage extent, such as a StorageVolume or LogicalDisk. 9, "Extent": Statistics for an intermediate storage extent, i.e. an extent that is neither a volume or a disk. 10, "Disk Drive: Statistics for a StorageExtent that is associated to a DiskDrive through the MediaPresent association. 11, "Arbitrary LUs": Statistics that derive from access to Logical Units that are NOT StorageVolumes (e.g., controller commands). 12, "Remote Replica Group": Statistics for control IOs between an array and a remote mirror across a Network. Note that statistics for the actual movement of data to the remote mirror are attributed to the targeted StorageVolume (or LogicalDisk). Note that a particular element could be associated to multiple BlockStorageStatisticalData instances if it had multiple roles. For example, a storage array could contain redundant component computer systems that communicate both with hosts on the front end and disks on the back end. Such a device could have one BlockStorageStatisticalData instance where ElementType=3 and another instance where ElementType=5.If only rated data is included per RateElementType, this property shall be set to 0.

IdleTimeCounteruint64
Counterbooleantrue
DescriptionstringThe cumulative elapsed idle time using ClockTickInterval units (Cumulative Number of Time Units for all idle time in the array).
IOTimeCounteruint64
Counterbooleantrue
DescriptionstringThe cumulative elapsed I/O time (number of Clock Tick Intervals) for all I/Os as defined in 'Total I/Os'. I/O response time is added to this counter at the completion of each measured I/O using ClockTickInterval units. This value can be divided by number of IOs to obtain an average response time.
KBytesReaduint64
Counterbooleantrue
DescriptionstringThe cumulative count of data read in Kbytes (1024bytes = 1KByte).
PUnitstringbyte * 10^3
UnitsstringKiloBytes
KBytesTransferreduint64
Counterbooleantrue
DescriptionstringThe cumulative count of data transferred in Kbytes (1024bytes = 1KByte).
PUnitstringbyte * 10^3
UnitsstringKiloBytes
KBytesWrittenuint64
Counterbooleantrue
DescriptionstringThe cumulative count of data written in Kbytes (1024bytes = 1KByte).
PUnitstringbyte * 10^3
UnitsstringKiloBytes
MaintOpuint64
Counterbooleantrue
DescriptionstringThe cumulative count of all disk maintenance operations (SCSI commands such as: Verify, skip-mask, XOR read, XOR write-read, etc).This is needed to understand the load on the disks that may interfere with normal read and write operations.
MaintTimeCounteruint64
Counterbooleantrue
DescriptionstringThe cumulative elapsed disk mainenance time. Maintainance response time is added to this counter at the completion of each measured maintenance operation using ClockTickInterval units.
ReadHitIOsuint64
Counterbooleantrue
DescriptionstringThe cumulative count of all read cache hits (Reads from Cache).
ReadHitIOTimeCounteruint64
Counterbooleantrue
DescriptionstringThe cumulative elapsed time for all Read I/Os read from cache for all cumulative Read I/Os.
ReadIOsuint64
Counterbooleantrue
DescriptionstringThe cumulative count of all reads.
ReadIOTimeCounteruint64
Counterbooleantrue
DescriptionstringThe cumulative elapsed time for all Read I/Os for all cumulative Read I/Os.
TotalIOsuint64
Counterbooleantrue
DescriptionstringThe cumulative count of I/Os for the object.
WriteHitIOsuint64
Counterbooleantrue
DescriptionstringThe cumulative count of Write Cache Hits (Writes that went directly to Cache).
WriteHitIOTimeCounteruint64
Counterbooleantrue
DescriptionstringThe cumulative elapsed time using ClockTickInterval units for all Write I/Os written to cache for all cumulative Write I/Os.
WriteIOsuint64
Counterbooleantrue
DescriptionstringThe cumulative count of all writes.
WriteIOTimeCounteruint64
Counterbooleantrue
DescriptionstringThe cumulative elapsed time for all Write I/Os for all cumulative Writes.
